Abstract excerpt
DNA aptamers that form a G-quartet conformation were covalently attached to a capillary surface for open-tubular capillary electrochromatographic separation of bovine beta-lactoglobulin variants A and B, which vary by 2 of their 162 amino acid residues. Separation was achieved using a 4-plane, G-quartet aptamer stationary phase with tris(hydroxymethyl)aminomethane (Tris) or phosphate buffer as the mobile phase....
